在docker中为python项目加载Teradata ODBC驱动程序时出错

Question

我正在尝试使用python teradata模块连接到Teradata数据库。但是当我在docker中运行我的应用程序时，我会遇到异常::

File "/usr/local/lib/python3.7/site-packages/teradata/udaexec.py", line 183, in connect
    **args))
  File "/usr/local/lib/python3.7/site-packages/teradata/tdodbc.py", line 421, in __init__
    init(odbcLibPath)
  File "/usr/local/lib/python3.7/site-packages/teradata/tdodbc.py", line 366, in init
    initOdbcLibrary(odbcLibPath)
  File "/usr/local/lib/python3.7/site-packages/teradata/tdodbc.py", line 319, in initOdbcLibrary
    odbc = ctypes.cdll.LoadLibrary(odbcLibPath)
  File "/usr/local/lib/python3.7/ctypes/__init__.py", line 434, in LoadLibrary
    return self._dlltype(name)
  File "/usr/local/lib/python3.7/ctypes/__init__.py", line 356, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: Error relocating /opt/teradata/client/16.20/lib64/libodbc.so: _toupper: symbol not found

我在我的Windows机器上运行相同的代码，但问题是我在Docker中运行相同的代码。在我的Windows机器上安装了Teradata ODBC 16.20，但是当我尝试在docker中做同样的事情时，我可能会错过一些东西，因为我是docker的新手。

Docker文件::

FROM python:alpine3.7

ADD test.py /
USER root
ADD tdodbc1620__linux_indep.16.20.00.54-1.tar.gz /tmp/
RUN apk add rpm
RUN rpm -ivh /tmp/tdodbc1620/tdodbc1620-16.20.00.54-1.noarch.rpm --prefix=/opt/ --nodeps    
RUN cp /opt/teradata/client/ODBC_64/odbc.ini ~/.odbc.ini
RUN cp /opt/teradata/client/ODBC_64/odbcinst.ini ~/.odbcinst.ini    
RUN pip install --upgrade pip
RUN pip install teradata        
ENV ODBCHOME=/opt/teradata/client/ODBC_64/ ODBCINI=/opt/teradata/client/ODBC_64/odbc.ini ODBCINST=/opt/teradata/client/ODBC_64/odbcinst.ini
ENV LD_LIBRARY_PATH $LD_LIBRARY_PATH:/opt/teradata/client/16.20/lib64    
RUN chown -R root /opt/teradata/client/16.20/lib64/*.so    
CMD [ "python", "./test.py" ]

Python代码::

import teradata

udaExec = teradata.UdaExec (appName="HelloWorld", version="1.0", logConsole=False)
session = udaExec.connect(method='odbc', system='xyz.com', username='xyz', password='xyz', AUTHENTICATION='LDAP')

with session as connect :
    for row in connect.execute("`select top 5 * from EMPLOYEE;`"):
        print(row)

预期结果::打印EMPLOYEE表中的前5行。

使用RHEL OS的Docker文件的最新副本：

FROM quay.********/rhel:latest

ADD test.py /

RUN yum --nogpgcheck -y install unzip sudo vim wget which tar gzip graphviz python-setuptools python-setuptools-devel shadow-utils git net-tools libXtst.x86_64 python-pip

RUN yum -y install libstdc++.so.6

ADD tdodbc1620__linux_indep.16.20.00.54-1.tar.gz ./

RUN cd /tdodbc1620/ &&  
    ./setup_wrapper.sh -s -r tdodbc1620-16.20.00.54-1.noarch.rpm

RUN  pip install teradata
